' ATTORNEY structure. The portions and positioned in a mannerto befreely moved and turned in any direction. The sheet metal structureprovides a light weight,non-bending, and unbreakable truck, which may bemanufactured at small cost, and is entirely reliable in operation.

In Figs. 6, to 10 there is illustrated a lIlOdlfiGCl form of theinvention, in which the pressed sheet metal frame or base comprises acircular dished portion provided with a flat base 22, centrallyapertured, as at 23, and having an outwardly inclined circular wall 24;extended upwardly in inclinedrelation at three spaced points and bentoutwardly to provide radially projecting. horizontally disposed castermounting portions 25, the bend being circumferential to. the center ofthetruck to provide a non-bending 25 are pressed into annularly groovedembossed circular portions 26, forming ball races at the under side, thecentral depressed portions within the races being apertured, as at 27,for 'securing the spindles of the casters. The cast er mounting portionsare further reinforced against bendingbymeans of downwardly bent flanges28' extending between the sides tion, but it will be obvious thatchanges may thereof and the circular wall 24. The casters each comprisesa'horn 29 rotatably supporting a caster wheel 30, and attached to theportion 26 of the truck frame by a spindle 31, having a central shoulder32 interposed between the top of the horn and the center of the portion26, and se" cured by heading over the endsas at 33 and. 34.Anti-friction balls 35 are interposed be: tween the top of the hornandlthe portion 26in the annular ball-race formed in the' latter,thereby providing a ball-bearinged caster structure. I a I haveillustrated and described preferred and satisfactory embodiments oftheinvenbe made therein, within the spirit and scope thereof, as defined inthe appended claims.

, Having thus described my invention, what I claim and desire to secureby Letters Patent is:

1. In a truck for stoves, or the like, a

shcet'metal frame including a central dished leg receiving portion,spaced radially 8X-' and reinforcing flanges extending along and edges'of said mounting.

connecting the side portions and said extension'portions at each side ofthe bend between them, and casters swivelly supported on said mountingportions. v z

3. In a truck for stoves,

leg receiving portionand spaced radiallyvextending caster mountingportions bent outwardly from said central portion, said mountingportions being centrally apertured and including pressed-up, annularchannels surrounding said apertures in spaced relation and providingball-races at the under sides of said mounting portions, .casters.swivelly supported on said mounting por-v tions including horns andspindles. secured in said apertures of said mountingportions, and ballsinterposed in said ball-race portions between the upper, sides [of saidhorns and said mounting portions.
